My elderly Mum has been too ill this year to grow tomatoes in her greenhouse, as she normally does, so I took over the job
for her, so she could still enjoy them. I'm very much a novice when it comes to greenhouses but we've had a really good tasty
crop, which is now drawing to a close. What I really need to know is, when should I start clearing out the plants from the
greenhouse? Some of the leaves are turning yellow, is that a sign that they are dying off, or is there some other reason?

tomato split is caused by heavy watering after the plants have become very dry, the fruit has a sudden growth spurt and splits its skin.

yellowing leaves are usually caused by a magnesium deficiency, you can spray the leaves with a solution of Epsom salts and water for immediate affect then prevent any more yellowing by using a fertilizer containing magnesium.

its probably a bit late in the season to bother now, but bear it in mind for next year

neither problems are really serious.

if you want to clear out the greenhouse you can dig up the plants and hang them upside down in a warm light place to ripen the last fruits.

Thanks Katee As you say its a bit late this year, but I'll certainly bear that information in mind for next years crop.
I tried to be organised with the watering, with it not being at my home, I didn't have full control. Some days, when I
was working, I asked my brother to water them when he visited our Mum, but he often forgot, so they did dry out a
bit sometimes. We fed them with Tomorite.....which I believe contains magnesium? Maybe not fed regularly enough.
Ah well....we've certainly enjoyed the crop we've had and there are still lots more freshly ripened ones each day!
